The police wont say they will back down but if there's 1,000 fans without tickets outside the ground they will let them in.
I think you're right and I'll happily stand with others and protest until they offer the opportunity to go in (which I suspect will be after the kick off), then I'll walk off to the pub anyway to make sure they've got to use as much of their resources as possible.
Sad but true. Ive left my protesting in the hands of my solicitor. WYP dont tell me where i can and cannot go. WYP dont make the law and from whats in the statute book there actions are un-lawful.
